Ideal based hypergraph of a commutative ring

AKCE International Journal of Graphs and Combinatorics, 2021
Let R be a commutative ring and k an integer strictly greater than 2. The k-maximal ideal hypergraph to R with vertex set the set of all k-maximal ideals in R and for distinct ideals I1, in the set is an edge of if and only if and the sum of any elements

Some Characterizations for Approximate Biflatness of Semigroup Algebras

Journal of Mathematics, 2023
In this paper, we study an approximate biflatness of l1S, where S is a Clifford semigroup. Indeed, we show that a Clifford semigroup algebra l1S is approximately biflat if and only if every maximal subgroup of S is amenable, ES is locally finite, and l1S

Logarithmic Negation of Basic Probability Assignment and Its Application in Target Recognition

Information, 2022
The negation of probability distribution is a new perspective from which to obtain information. Dempster–Shafer (D–S) evidence theory, as an extension of possibility theory, is widely used in decision-making-level fusion.

Elements of Maximal Order in Finite p-Groups [PDF]

Proceedings of the American Mathematical Society, 1972
Let G be a finite p-group such that every 3-generator subgroup has class at most p. If K(G) denotes the subgroup of G generated by the elements of maximal order in G, then K(G) has index at most p in G. G. Zappa proved [5] that if G is a finite p-group of class at most p, then H,(G) has index at most p in G, unless H,(G)= 1.

Clinical and Biological Features of Response in Resistant Neuroblastoma to 131I‐Metaiodobenzylguanidine Radiotherapy in the Anti‐GD2 Immunotherapy Era

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background 131I‐metaiodobenzylguanidine (131I‐MIBG) radiotherapy is a key treatment for relapsed and refractory (R/R) neuroblastoma (NB). Patients with R/R disease treated in the modern era are increasingly exposed to anti‐GD2 immunotherapy, which exerts selective pressure and may modify both tumor cell state and microenvironment.

Maximal elements for non-ordered preferences

, 1992
Using Reich’s [1] definition of the measure of noncompactness for locally convex spaces, we extend a recent result of Mehta [2], on the existence of maximal elements for nonordered preferences defined on a noncompact set, from Banach spaces to a larger ...

Heterogeneity in the Global Practice of Central Nervous System Staging in Pediatric Acute Lymphoblastic Leukemia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Central nervous system (CNS) involvement in childhood acute lymphoblastic leukemia (ALL) is assessed by cell counting and cytomorphology from cerebrospinal fluid (CSF) and is used for treatment stratification worldwide. The ratio of “CNS2” patients in clinical trials ranges from 3% to 40%, with unclear prognostic significance ...

Maximal elements and equilibria of generalized games for 𝒰-majorized and condensing correspondences

International Journal of Mathematics and Mathematical Sciences, 1999
In this paper, we first give an existence theorem of maximal elements for a new type of preference correspondences which are 𝒰-majorized. Then some existence theorems for compact (resp., non-compact) qualitative games and generalized games in which the ...

Monoids and Maximal Codes [PDF]

Electronic Proceedings in Theoretical Computer Science, 2011
In recent years codes that are not Uniquely Decipherable (UD) are been studied partitioning them in classes that localize the ambiguities of the code. A natural question is how we can extend the notion of maximality to codes that are not UD.

Therapeutic Apheresis for Intravenous Methylprednisolone‐Refractory Neuromyelitis Optica Spectrum Disorder: Clinical and Radiological Outcomes in a Single‐Center Case Series

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Neuromyelitis optica spectrum disorder (NMOSD) is a relapsing autoimmune disease of the central nervous system. High‐dose intravenous methylprednisolone (IVMP) is the standard first‐line therapy for acute attacks, although some patients remain refractory.
